I worked with this team while at my previous firm, but they had their own office space that was completely separate from us (and our co).
They were very organized about getting things done quickly to get projects out of town completed before we left! The only thing really bad is how much time it takes them sometimes because there are so many steps involved just moving one file or folder around. Also if you don't have an account set up then can take some times as well since its not always easy to find what files/folders need moved when working off email alone instead using physical folders etc.. But overall great people doing GREAT work!! We used these guys primarily during the buildout phase once new building came online - everything related to hardware installation like networking switches /cabling /wiring rooms ect...
